Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a gondola suitable for use with a cover sheet attached in wall construction of buildings, structures, etc.

(Prior Art) Conventionally, gondolas used by workers in wall painting or wall cleaning of buildings, structures, etc., have been used to move the gondola body vertically relative to the parapet of a tower building. There is something that moves.

When painting the walls of a building, it has traditionally been used to prevent paint powder from scattering around due to the effects of wind, etc., and to prevent the paint that has been applied to buildings, etc. from being inadvertently stained. The entire building was covered with a cover sheet, regardless of the gondola.

(Problems to be solved by the invention) The conventional cover sheet installation method that adopts the above-mentioned entire surface installation method requires a lot of time and effort to install the cover sheet in addition to the installation of the gondola body. In addition, the equipment costs for preparing a large cover sheet that covers the entire building were also becoming expensive.

Furthermore, the gondola itself was dangerous because the other three sides facing the wall of the building were not covered in any way, so it was easily affected by wind and the like, and uneven coating was likely to occur on the coated surface.

The object of the present invention is to provide a gondola which attempts to solve the conventional drawbacks in wall construction of buildings.

(Means for Solving the Problems) Therefore, the present invention is to attach holding fittings to the parapet of a building tower at regular intervals, and to install a rail for suspending the gondola main body on the holding fittings parallel to the parapet, The gondola body is suspended from a required number of pulleys that are freely rollable on the rails via desired coupling devices, thereby making the gondola body movable up and down and left and right. A lower rail is provided on the ground section in opposition to the lower rail substantially parallel to the lower rail, a lower connector is slidably provided on the rail, and an upper connector is slidably provided on the upper rail. A pair of wires is movably stretched through the upper and lower connecting devices, and the wires are crossed in a pipe that has guide pulleys at the upper and lower left and right ends and opposing brackets at the left and right inner ends. A cover sheet is detachably attached to the pipe and the bracket as required, and is hung to cover the gondola body.

(Example) The present invention will be described in detail below based on the attached drawings showing examples.

Fig. 1 is a side view of the mounting mechanism of the gondola of the present invention, Fig. 2 is a perspective view of the holding fitting part that constitutes this embodiment, Fig. 3 is a side view showing the mounting state of the holding fitting, and Fig. 4. A front view of the same is shown.

In the figure, the gondola mounting mechanism of the present invention connects a pair of rods 1, one side of which is formed into a U-shaped bent part 1a, and the other side of which is formed into a hook-shaped bent part 1b facing downward. Holding fittings A consisting of the above are fixed to the parapet B of the building tower at regular intervals, and a rail 2 is erected parallel to the parapet B on the protruding end 1c of the U-shaped bent portion 1a formed on the holding fitting A. The gondola main body C is constructed by placing a pulley 3 on a rail 2 so as to be able to roll freely, and suspending a gondola main body C from a hanging rod 5 fixed to the pulley 3 via a connector 4.

In this configuration, the pair of rods 1 forming the holding fitting A are round rods with sufficient strength, and are coated with rubber to prevent rust and damage to the parapet B due to direct contact. etc. will be carried out. In addition, in order to assist the U-shaped bent portion 1a, an auxiliary plate (or bar) is provided between the U-shaped parallel bars.
6 is fixed by welding or the like. The holding fitting A connects and secures the pair of rods 1 at the front rising portion 1a' of the U-shaped bent portion 1a with a connecting rod 7, and also connects and secures the pair of rods 1 at the hook-shaped bent portion 1b with a connecting rod 8. Strongly formed.

Therefore, in order to attach the holding fitting A to the parapet B, the U-shaped bent portion 1a of the rod 1 is attached to the parapet B.
straddle the upper surface of the parapet B at the horizontal part 1d so that the hooked bent part 1b faces the rear wall, and fix the hooked bent part 1b to the rear wall of the parapet B with bolt nuts 9. This is done by means such as

Further, when it is necessary to further reinforce the U-shaped bent portion 1a of the rod 1, it can be supported by brackets 10, 11, etc., and the U-shaped bent portion 1a can be reinforced using a wire (not shown). It can also be secured to a suitable metal fitting fixed to the. When attaching the holding fitting A, the parapet B is protected by interposing a metal plate 12 lined with a cushioning material such as a rubber plate at the contacting or fixed portion with the parapet B.

Next, the rail 2 is installed on the holding fitting A by the following method. In other words, on parapet B
The rail 2 is made of a round bar or the like with a length corresponding to the center distance between the holding fittings A attached at intervals of about 1 m, and with male and female threads carved on both ends. Prepare multiple copies. This rail 2 is placed on the protruding end 1c of the holding fitting A as shown in FIG. do. In addition, a fixing band 1 is attached to this screwed portion in order to prevent the rails 2 from coming off each other due to loosening of the screwed portion, and to reinforce the screwed portion.
3 is tightened. As shown in FIG. 5 along the line A-A in FIG. grip part 13
b, 13c are provided, and the upper end gripping part 13b is formed to be openable and closable with respect to the lower end gripping part 13c to which the bottom part is connected.
This is done by fitting the lower end gripping portion 13c onto the connecting rod 7, then fitting the upper end gripping portion 13b into the threaded portions of the rails 2, and then screwing the connecting portion 13a with the bolt nut 14.

Next, as shown in FIG. 6 in a partial front view and FIG. 7 in a sectional view taken along line B-B in FIG. A pair of pulleys 3 are mounted, and a hanging rod 5 is fixedly suspended from the pulleys 3 via a connector 4. That is, the connector 4 is formed of a plate having a U-shaped cross section with one side longer than the other, and this U-shaped portion is placed over the pulley 3.
The connecting tool 4 is fixed to the pulley 3 by passing the support shaft 15 through the axis of the pulley 3 and the U-shaped portion. Further, a pulley driving motor 16 is attached to one side of the pulley 3 via a connector 4. Note that the motor 16 may be attached to only one of the pair of pulleys 3.

The gondola main body C is suspended from the hanging rod 5 via a wire rope 17 so as to be vertically movable by means of a known combination of a winder and a brake motor (not shown).

FIG. 8 shows a state in which the gondola main body C is suspended from the tower of the building D using the mounting mechanism of the present invention having the above-described configuration.

In addition, in order to prevent the scattering of paint etc. applied to the wall surface of a building, a cover sheet E is attached to the horizontal movement mechanism of the gondola body C described above so as to be movable left and right at the same time as the gondola body C, if necessary.

That is, the cover sheet E is attached as follows. First, as shown in FIG. 1, the support bracket 18 is mounted and fixed on the upper part of the coupling tool 4 of the pair of pulleys 3, and the wires 19a and 1 are respectively inserted from the front end of the support bracket 18.
9b is suspended, and its lower end is connected and fixed to a connecting tool 20 installed on the ground so as to be movable from side to side. This connector 20 has the same configuration as the connector 4 described above, and its left and right movement is achieved by fixing an inverted U-shaped rail 22 to the bridge between a plurality of supports 21 provided on the ground with the rail surface facing downward. , Connector 2 is attached to this rail surface.
This is accomplished by mounting a pulley 23, which is connected to the connectors 0 by the same means as the connector 4, so as to be movable from side to side.

The cover sheet E has this pair of wires 19a, 1
It is installed between 9b and 9b so that it can be raised and lowered freely. An example of this mounting mechanism is shown in FIG. That is, a square pipe 24 having a pair of guide pulleys 25a, 25b and guide pulleys 26a, 26b attached vertically at both ends is arranged horizontally between a pair of wires 19a, 19b, and one wire 19a is attached to the guide pulleys. The wire 19b is passed through the inside of the square pipe 24 through the guide pulley 26b and suspended underground via the guide pulley 26b, and the other wire 19b is passed through the inside of the square pipe 24 through the guide pulley 26a so as to intersect with the wire 19a. It is passed through and suspended to the ground via the pulley 25b. Furthermore, brackets 27 which can be folded freely with respect to the square pipe 24 are provided projecting from both ends of the square pipe 24 via hinges. Thus, the cover sheet E is removably attached to and hangs down from the square pipe 24 and the bracket 27 at its upper edge.
Further, a plurality of rings 28 are attached in the vertical direction to the portion facing the wires 19a, 19b, so that the wires 19a,
19b is inserted through these rings 28.

Note that when it is necessary to reinforce the support bracket 18 that is fixed to the top of the connector 4, a plurality of columns 29 are placed on the tower, and these columns 29
A wire 30 is stretched parallel to the rail 2 between them, a pulley 32 to which a connecting tool 31 similar to the connecting tool 4 is fixed is attached to the wire 30, and the connecting tool 31 and the support bracket 18 are connected by a wire 33. This can be done by separately installing a means to do so. In this case, instead of rolling the pulley 32 on the wire 30, a round tube connected to the wire 33 is moved onto the wire 30.
It may also be made to slide inside.

The embodiment of the present invention has the above configuration, and in FIG. 8, the gondola main body C can be freely moved up and down in the directions of arrows A and B with respect to the building wall by known means, and in the directions of arrows C and D. The left and right movement of the pair of pulleys 3 can be easily performed by an operator driving the motor 16 of the pulley 3 by operating a switch on the gondola main body C.

Further, the cover sheet E is also automatically moved left and right in conjunction with the left and right movement of the gondola body C. Furthermore, when it is desired to move the cover sheet E up and down, the operator moves the square pipe 24 up and down on the gondola body C to move the upper edge of the cover sheet E to an arbitrary position at a position that covers the gondola body C and at the same time as above the ground. It can be stopped at a desired height position. Further, since the gap between both sides of the gondola main body C and the building is covered with a cover sheet hanging from the bracket 27, scattering of paint caused by painting work etc. is completely prevented. In addition, in the case of strong winds, etc., by removing the cover sheet E from the square pipe 24 and the bracket 27, the ring 28 can be attached to the wires 19a, 1.
9b and can be easily removed.

(Effects of the invention) As explained above, according to the gondola mounting mechanism of the invention, the gondola itself can be automatically moved not only vertically but also horizontally relative to the building wall without the need for complicated replacement work. However, as the gondola body moves vertically and horizontally relative to the building wall, the cover sheet attached to cover the gondola body can be moved vertically and horizontally together with the gondola body. This makes it possible to install the minimum necessary amount. Therefore, the work of laying the cover sheet can be greatly omitted, reducing time and labor, resulting in a significant reduction in personnel and equipment costs.Also, the painting of building walls, etc. is not affected by wind, etc., and can be kept the same. Since the coating can be applied under certain conditions, uneven coating will not occur, and scattering of the smear to the surrounding area can be reliably prevented, and furthermore, the appearance can be improved.

In addition, when working with conventional gondolas, workers tend to lean out of the gondola in order to finish a large area at once, which is extremely dangerous, but with the present invention, the gondola is covered with a cover sheet, and the gondola is shaken. Since movement is prevented, work safety is increased.
